      [POWERPC] Add IRQ remapping hook · acc900ef
      由 Ishizaki Kou 提交于 
      This patch adds irq remapping hook. On interrupt mechanism on Beat,
when an irq outlet which has an id which is formerly used is created,
remapping the irq is required.

      [POWERPC] Move ELF_ET_DYN_BASE up to 512MB point · 7e60d1b4
      由 Anton Blanchard 提交于 
      I often test new versions of glibc by doing:

LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary>

One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded
at 0x8000000 (128MB) with the heap right after it. Since we normally
link binaries at 0x10000000 (256MB) we only had about 128MB of space for
the heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]
08000000-0801e000 r-xp 00000000 00:01 33079       /lib/ld-2.5.so
0802d000-0802f000 rwxp 0001d000 00:01 33079       /lib/ld-2.5.so
0802f000-08050000 rwxp 0802f000 00:00 0           [heap]
0fe91000-0ffd9000 r-xp 00000000 00:01 33082       /lib/libc-2.5.so
0ffd9000-0ffe8000 ---p 00148000 00:01 33082       /lib/libc-2.5.so
0ffe8000-0ffea000 r--p 00147000 00:01 33082       /lib/libc-2.5.so
0ffea000-0ffed000 rwxp 00149000 00:01 33082       /lib/libc-2.5.so
10000000-10004000 r-xp 00000000 00:01 76          /bin/sleep

ffb41000-ffb56000 rw-p ffb41000 00:00 0           [stack]

One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
This allows 128MB for the binary (hopefully enough for even the most
crazy c++ apps), and with our current layout we will grow the heap up
and the stack down, allowing potentially gigabytes of heap:

      [PATCH] x86: fix PDA variables to work during boot · 9ee79a3d
      由 James Bottomley 提交于 
      The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.

The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id.  The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.

The fix is to be careful and actually do the GDT setups correctly.

      [POWERPC] atomic_dec_if_positive sign extension fix · 434f98c4
      由 Robert Jennings 提交于 
      On 64-bit machines, if an atomic counter is explicitly set to a
negative value, the atomic_dec_if_positive function will decrement and
store the next smallest value in the atomic counter, contrary to its
intended operation.

The comparison to determine if the decrement will make the result
negative was done by the "addic." instruction, which operates on a
64-bit value, namely the zero-extended word loaded from the atomic
variable.  This patch uses an explicit word compare (cmpwi) and
changes the addic. to an addi (also changing "=&r" to "=&b" so that r0
isn't used, and addi doesn't become li).

This also fixes a bug for both 32-bit and 64-bit in that previously
0x80000000 was considered positive, since the result after
decrementing is positive.  Now it is considered negative.

Also, I clarify the return value in the comments just to make it clear
that the value returned is always the decremented value, even if that
value is not stored back to the atomic counter.

      libata: initialize qc->dma_dir to DMA_NONE · 501e0c50
      由 Tejun Heo 提交于 
      libata didn't used to init qc->dma_dir to any specific value on qc
initialization and command translation path didn't set qc->dma_dir if
the command doesn't need data transfer.  This made non-data commands
to have random qc->dma_dir.

This usually doesn't cause problem because LLDs usually check
qc->protocol first and look at qc->dma_dir iff the command needs data
transfer but this doesn't hold for all LLDs.

It might be worthwhile to rename qc->dma_dir to qc->data_dir as we use
the field to tag data direction for both PIO and DMA protocols.

This problem has been spotted by James Bottomley.

      由 Trond Myklebust 提交于 
          NFS: Fix race in nfs_release_page()

    invalidate_inode_pages2() may find the dirty bit has been set on a page
    owing to the fact that the page may still be mapped after it was locked.
    Only after the call to unmap_mapping_range() are we sure that the page
    can no longer be dirtied.
    In order to fix this, NFS has hooked the releasepage() method and tries
    to write the page out between the call to unmap_mapping_range() and the
    call to remove_mapping(). This, however leads to deadlocks in the page
    reclaim code, where the page may be locked without holding a reference
    to the inode or dentry.

    Fix is to add a new address_space_operation, launder_page(), which will
    attempt to write out a dirty page without releasing the page lock.
